Plumbers and heating engineers
More Google reviews for plumbers and heating engineers
A customer only reacts once the crisis has passed, not before. A plumber or heating engineer who wants reviews consistently asks at that moment: for an emergency callout, once the water stops or the boiler fires up again and the invoice has gone out, with a WhatsApp message after payment; for a scheduled job, at the pressure test or start-up itself, with an SMS at handover and the invoice as a reminder afterwards.
- For an emergency callout, send the request after payment, not with wet hands in the cellar.
- For a scheduled job, ask at handover: WhatsApp or SMS, with the invoice following as a reminder.
- One reminder if a customer does not reply, then the follow-up stops on its own.

Why do Google reviews weigh so heavily for a plumber or heating engineer?
Anyone with a leak or a broken boiler searches Google Maps straight away and picks from a short list almost every time. The rating, the number of reviews and how recent the latest one is together decide whether you survive that list. With thousands of installation businesses in Belgium, that is the first filter a customer applies, before price or availability even come into it.
Belgian consumer sites warn about a recognisable pattern: an installer who inflates a problem, a quote that seems pulled from nowhere, pressure to pay cash, and no company number or written quote. Anyone who knows that pattern reads reviews as the first check that you are not one of those.
Add the labour shortage on top. Self-employed plumbers and heating engineers usually work alone or in twos, sometimes father and son, sometimes two partners. Many firms trying to hire staff give up and subcontract instead. Whether the search starts in Antwerp or in a small village, that list on Maps works the same way.
- Rating: the number shown next to your name in a list of three or four.
- Count: how many customers back that rating up.
- Freshness: is the latest review from this month or from before the pandemic?
- Replies: whether you respond, and how.
When do you ask: at the callout or at the scheduled job?
For an emergency callout, you do not ask on the spot, with wet hands in a cellar or a crawlspace. You ask once the water stops or the boiler fires again and the invoice is sent. For a scheduled job, the moment is the pressure test, when the customer sees the working system and your tools half packed away.
Faced with a leaking pipe or a boiler that has cut out, your hands are dirty or wet, your toolbag half empty on the floor, and the customer watches, relieved, as the water stops. That relief is real, but the customer is still mid-crisis: they are thinking about the damage, not about Google. Ask nothing there. Send a message instead once you are back in the van and the invoice is drawn up.
For a scheduled installation, a new boiler or a full bathroom, the moment is different. The last step is the pressure test: you show the customer the system running, the radiators heating up, the tap no longer dripping. That is the point where they are satisfied and still standing there. The invoice often follows days later, and by then that moment has passed.
Why do plumbers and heating engineers keep missing reviews?
An emergency callout is over within the hour: paid, packed up, gone, no second to ask anything. A scheduled job splits the thank-you moment from the paperwork, because the invoice arrives days later by email or post. By then the moment is cold and the customer no longer thinks about the plumber or heating engineer from that week.
Ask a self-employed plumber why they never ask for a review, and you hear the same three things every time. "I do not have time between two jobs." "My customers are older, they do not do that." "I am standing with dirty hands in a cellar, I am not pulling out a phone there." All three are true, at the moment of the job itself.
Fear plays a part too. Someone self-employed who has just had a disagreement about the bill is not keen to ask that same customer for their opinion. A bad review at the wrong moment feels like a risk that is not worth the trouble of asking.
What if a customer uses a bad review to avoid paying?
A customer who does not want to pay sometimes threatens a one-star review to apply pressure. Do not engage with that publicly: never discuss the invoice under the review itself. Reply briefly and calmly, point to a direct conversation, and leave it there. Anyone reading it sees a threat, not evidence.
The pattern is familiar: a quote that comes in higher than expected, a disagreement over extra work, and a message that they will "leave a review" unless you budge. Never respond to the substance under the review itself: commenting publicly on it confirms there is something to argue about.
Reply briefly: you are aware of the situation, you would rather talk it through directly, and give a phone number or email address. No figures, no accusations. A calm reply looks professional, a heated one confirms the picture the customer is trying to paint.
This trade is particularly exposed to that picture. Belgian consumer sites describe a pattern of an inflated diagnosis, an exorbitant quote, pressure to pay cash and no written quote. One angry review that happens to match that list is read not as one opinion, but as confirmation of what the reader was already warned about.
How does ReviewsPro fit into the working day of a plumber or heating engineer?
You send the request by WhatsApp or SMS as soon as the invoice goes out, not while you are still packing up your tools. The app remembers who has already been asked, sends one reminder if nobody replies, and a partner or employee can follow up without needing your phone.
- WhatsApp or SMS: a name and a mobile number are enough to send the request once the invoice goes out, no email needed.
- QR code: a sticker on the boiler, useful as a visual reminder, though you only see most customers once.
- Follow-up: one reminder if a customer does not reply, then it stops on its own.
- Team: your partner or your son can follow up without needing your phone.
Nothing changes about your invoicing, your schedule or your job sheet. ReviewsPro only comes in once the invoice is ready, not before.
What can you realistically expect from asking for reviews?
Expect steady progress, not a sudden flood. We promise no number: it depends on how many jobs you run and how your customers respond. What does hold is that a message sent after every invoice gives a steadier rhythm than asking occasionally.
Nobody posts a review off their own back after a leak gets fixed at six in the evening. Sending a message after every invoice, whatever the week looks like, keeps that collection steady, even though far from everyone replies.
| Asking now and then | A fixed flow after the invoice | |
|---|---|---|
| Who asks | You, if you remember between jobs | The invoice, every time |
| Timing | Variable, sometimes days later | Straight away when the invoice goes out |
| Follow-up | Nobody knows who was already asked | Visible in the app |
| Rhythm | Random, after a good week | Steady, no spikes |
Set a rhythm you can keep up alongside the work itself, and measure it against your own previous month rather than a figure from a brochure. Google names prominence as one of the three local ranking factors, alongside relevance and distance, and your reviews are the part of it you actually hold.
Frequently asked questions
Can I ask a customer for a Google review after the invoice, as a plumber?
Yes. You can always ask a customer for a Google review, including after the invoice, as long as you ask everyone the same question and give nothing in return. Ask every customer the same way, not only the ones you think were happy. Paying or rewarding someone for a review is not allowed: Google’s own policy bans it. Writing a review yourself, or having staff or family write one, is not allowed either: those are fake reviews. You are messaging a customer you have just served, on a number they gave you for that job: say who you are, keep it to one message plus one reminder, and stop as soon as someone asks you to.
How do I respond to a negative review from a customer who will not pay?
Briefly and calmly, without discussing the invoice. Acknowledge that there is a disagreement, say you would rather talk it through directly, and give a phone number or email address. Do not get into amounts or extra work under the review itself, because that confirms for every reader that there is something to dispute. You are not writing for that one customer, you are writing for whoever hesitates after them.
Can I get a review removed that is being used as leverage to avoid paying?
Usually not. Google removes a review if it breaks its own policy, for instance because there is no genuine customer relationship behind it. A disagreement about a price is not a policy breach, even if the review is clearly meant as pressure. You can report it through your Google Business Profile, but do not expect a quick removal. Your reply underneath carries more weight than the report itself.
What if a review makes a technically incorrect complaint about my work?
Reply factually, in terms a layperson can follow. Explain in two sentences what actually happened on a technical level, without making the customer look foolish. Offer to come and take a look, or to show a camera inspection or a compliance certificate. Anyone reading that sees a tradesperson who can explain their work, not someone who is defensive.
How many Google reviews do I need to stand out against big installation firms as a sole trader?
There is no fixed number, not even for a good heating engineer. What matters is that your reviews are recent and that your rating sits close to a bigger firm’s. A sole trader with a handful of fresh reviews each month often looks more active than a firm with a long list whose latest review is months old. Regularity outweighs count.
Does a QR code work for a heating engineer who always works at the customer’s home?
Partly. A sticker on the boiler or the service card works as a visual reminder, but you are usually already gone before the customer does anything with it. The real work happens through WhatsApp or SMS after the invoice: that message reaches the customer for certain, while they are at home and not hunting for a sticker they forgot about long ago.
